every codebase has files that are dying. find them.

---

deathbed analyses every tracked source file in a git repository and gives it a health score based on six real, local metrics — no external API calls, no secrets needed. It then surfaces the files most likely to cause you pain, explains why they are dying, and tells you exactly what to do first.

---

Why?

Every codebase accumulates rot. Files that nobody owns. Files too complex to understand. Files last touched three years ago by someone who left. These files never show up in sprint planning, but they quietly cause the most bugs, the slowest onboarding, and the worst incidents.

deathbed makes the invisible visible.

Install

pip install deathbed

Or, to hack on it:

git clone https://github.com/NikoloziKhachiashvili/deathbed
cd deathbed
pip install -e .

Usage

# Analyse the current git repo
deathbed

# Analyse a different repo
deathbed --path /path/to/repo

# Show only the 20 worst files
deathbed --top 20

# Show only WARNING and CRITICAL files (score < 65)
deathbed --min-score 65

# Output JSON for CI pipelines / scripting
deathbed --format json

# Combine flags
deathbed --path ~/projects/myapp --top 10 --format json

Options

Flag	Default	Description
--path, -p	.	Path to the git repository
--top, -t	50	Show only the N worst files (0 = all)
--min-score	—	Only show files with a health score below this value
--format, -f	rich	Output format: rich or json
--version, -V	—	Show version and exit

What it looks like

When you run deathbed you get:

Metrics explained

Each file receives a composite health score from 0–100 (higher is healthier), built from six weighted sub-scores:

#	Metric	Weight	What it measures
1	Size	15%	Lines of code — penalises files > 300 / 600 / 1000 lines
2	Age	20%	Days since any commit touched this file — flags abandoned code
3	Churn	20%	Number of commits to this file — instability signal
4	Complexity	20%	Radon cyclomatic complexity average — Python files only; N/A otherwise
5	Authors	15%	Unique git authors — many authors = diffused ownership
6	Test coverage	10%	Whether a corresponding test file exists anywhere in the repo

Health thresholds

Score	Status	Meaning
86–100	✅ HEALTHY	All good
66–85	🌡 FAIR	Minor issues
41–65	⚠️ WARNING	Needs attention soon
0–40	💀 CRITICAL	Actively dangerous

Diagnoses

deathbed automatically picks the most meaningful single-phrase diagnosis:

Diagnosis	What it means
complexity graveyard	Cyclomatic complexity is extremely high
legacy ghost	Not touched in years — likely orphaned
too many cooks	Many authors, nobody owns it
churn monster	Modified constantly — unstable abstraction
growing out of control	Large and getting larger
nobody's watching this	Old code with no test coverage
abandoned and complex	Old and hard to understand
healthy	Nothing to worry about

JSON output

--format json returns a machine-readable object useful for CI gates:

  "repo": "/path/to/repo",
  "total": 3,
  "files": [
    {
      "file": "src/legacy/monster.py",
      "health_score": 22,
      "status": "CRITICAL",

      "lines": 1284,
      "days_since_commit": 847,
